Abstract: Floating device for harnessing swell energy by lateral overflow, said device being formed by hulls which converge in plan view and have a variable freeboard between which the waves propagate. The convergence produces a gradual increase in the height of the wave as it propagates between the hulls, which, together with the reduction in the freeboard from a particular section of said hulls, gives rise to the lateral overflow of the mass of water of the crest over their rails, which is collected in tanks which are at different heights (in accordance with the reduction in the freeboard) and are connected to the corresponding turbines. The angle of convergence between the hulls can be varied in order to be adapted to the sea state. The harnessing system is supplemented with a connecting closure ramp between the sterns of the hulls in order to collect the water which has previously not managed to overflow the structure.
